1974 C10 brake proportioning valve wiring *Pictures requested*

[74ChevC10Cruizn]

Would anyone be willing to post a picture of the proportioning valve and the wiring plug that connects to it from a bracket off of the frame?

Just finished wiring my new complete harness and don't remember how it was previously wired to the proportioning valve and what the bracket looked like.

This is on a 1974 K10, as I recall it just bolts to the frame.

My daughter is out of town this week or I'd run over and take a pic of her 1973 C30.

I do know the wire "Y"s off at the firewall plug going back, one branch goes to the ignition switch and one goes to the cluster.

I can run out to my k10, the valve next to power steering pump?

What happens if this isn’t plugged in?

What happens if this isn’t plugged in?

Assuming it's the same as an '81, the brake warning light doesn't light up. I unplugged mine to pass inspection. I need to replace my proportioning valve.

The wire that connects to the prop valve is a short jumper that runs over to a bracket mounted on the frame near the ps pump. In the second pic you can see the jumper connector (removed from prop valve) and the bracket.
